“…When wasps were offered puparia of S.argyrostoma, for example, the RDN for long-night accumulation was relatively short (about 10) and diapause incidence high, whereas with puparia of Calliphora erythrocephala the RDN was lengthened (to 15) and the incidence of larval diapause lowered . Similar effects have been noted in the mosquitoes Aedes triseriatus (Clay & Venard, 1972) and A.atropalpus (Beach, 1978), in which starvation or an inadequate diet protracted the larval sensitive period, allowed them to accumulate a greater number of long nights, and increased diapause.…”

ABSTRACT. Insect photoperiodic responses are complex and variable, but all involve a ‘clock’ which is used to determine the qualitative difference between long and short nights, and a ‘counter’ mechanism which accumulates successive long (or short) nights quantitatively up to an internal threshold at which induction (of diapause, seasonal morphs, etc.) is ‘complete’. The clock is circadianbased in at least seven species; in others a non‐oscillatory ‘hour‐glass’ device is indicated, but negative ‘resonance’ experiments may not necessarily rule out a circadian involvement in time measurement. The counter is temperature‐compensated. In some species it adds up long nights, in some short nights, and in others long and short nights. The proportion of the population entering diapause is dependent on an interaction between the temperature‐compensated counter and temperature‐dependent rates of development; this interaction explains many of the known effects of temperature, diet, and latitude in insect photoperiodic responses. In formal terms, the accumulation of long nights is seen as an increase in a ‘diapause titre’ which is compared with an individual internal threshold. In concrete terms, this ‘titre’, and the counter mechanism, might be represented by the accumulation of neurosecretory granules within the neuro‐endocrine system.

ABSTRACT. Embryonic diapause of the silkworm, Bombyx mori, is generally induced by temperature and photoperiod during the egg stage of the previous generation and not in the larval stage. However, when silkworm larvae are reared on an artificial diet instead of mulberry leaves, their diapause is strongly affected by temperature and photoperiod experienced in the larval stage, with a distinct long‐day response for diapause induction. Moreover when larvae which have been reared on artificial diet under long‐day condition are fed mulberry leaves even for a short period of time, most of the resultant female adults lay diapause eggs. These results suggest that the photoperiodic response of larvae for diapause induction may be strongly suppressed by some components in mulberry leaves.

“…Temperature similarly modifies the dormancy-inducing effect of short daylengths in other mosquitoes that overwinter as larvae (e.g. Aedes triseriatus (Say) (Vinogradova 1967a;Clay and Venard 1972); Anopheles plumbeus Stephens (Vinogradova 1962); Anopheles bifurcutus L. (Vinogradova 1963)). By contrast, Evans and Brust (1972) found that the photoperiodic response of perature.…”

Geographic variation in the effects of temperature and photoperiod on dormancy induction, development time, and predation in the tree-hole mosquito, Toxorhynchites rurilus septentrionulis (Diptera: Culicidae). Can. J. Zool. 57: 1612-1618. Critical daylength for dormancy induction was similar for laboratory colonies of a northern (Delaware) and a southern (Louisiana) population of Toxorhynchire.~ rutilus septentrionalis. The threshold daylength for dormancy induction was greater in the northern population and the photoperiodic response of the northern population was less affected by high temperature.Although photoperiod did not affect the duration of preadult development in the southern population, the duration of preadult development of the northern population varied in a nonlinear fashion with photoperiod at 27' C and increased with decreasing daylength at 19°C.The duration of the third instar was consistently longer in dormant than in active larvae of both populations.The pattern of prey consumption during larval development was similar in dormant and active larvae. Prey consumption terminated 24h prior to pupation in active larvae; dormant larvae continued to feed at a low rate. Similar numbers of prey were consumed during development by active and dormant larvae.The differences in the biologies of the two populations are discussed in relation to climatological differences in the environments from which each population was derived.

Toxorhynchites rurilus septentrionalis (Diptera: Culicidae). Can. J . Zool. 57: 1612-1618. Chez Toxorhynchires rutilus septentrionalis, le declenchement de la dormance est fonction d'une photoperiode critique qui est la mCme chez les colonies experimentales issues d'une population du nord (Delaware) et chez celles issues d'une population du sud (Louisiane). Chez la population nordique, la photoperiode-seuil est plus longue et la reaction i la photoperiode est moins affectee par des temperatures elevees.La photoperiode n'affecte pas la duree du developpement pre-adulte, chez la population du sud, mais, chez la population nordique, la duree du developpement pre-adulte varie avec la photoperiode selon une fonction non lintaire a 2PC, alors qu'8 IYC, cette duree augmente a mesure que diminue la photoperiode.Chez les deux populations, la duree du troisieme stade est toujours plus longue chez les larves en dormance que chez les larves actives.La consommation des proies se fait selon des courbes semblables chez les larves en dormance et chez les larves actives. La consommation de proies cesse 24 h avant la nymphose chez les larves actives; les larves en dormance continuent de se nourrir un peu. Durant le developpement, les larves actives et les larves en dormance consomment B peu pres le mCme nombre de proies.La discussion porte sur les differences biologiques des deu...
